Application filed May 22, 1906. sem No. 318,276.

To aZZ whom it may concern:

Be it known that I, CALVINN. PAYNE, a citizen of the United States,residing at Titusville, in the county of Crawford and State ofPennsylvania, have invented new and useful Improvements inSpeed-Changing Devices, of which the following is a specification.

This invention relates to speed changing devices and consists in certainimprovements in the construction thereof as will be hereinafter fullydescribed and pointed out in the claims.

This invention is particularly adapted to speed changing devices usedwith automo biles and is shown as designed for this use.

Among the important features 'of the invention are devices through whichvarious speeds may be brought into action through the continuousmovement of the controlling mechanism in one direction. Mechanism foreach speed may be coupled up or released by the movement of thecontrolling mechanism either to the next higher speed or next lowerspeed and the movement of, the controlling mechanism in either directionautomatically releases the mechanism just previously in action. v

The device also contains mechanism adapted to be thrown into and out ofaction by the same controlling mechanism for directly connecting thedriving and driven shaft and when so connected, the remaining mechanism.

is thrown entirely out of action automatically.

Other features of the construction w ill appear from the specificationand claims.

The invention'is illustrated in the accomg panymg drawings as follows:

Figure 1 is a section on the line 11 in Figs. 3, 4:, 5 and 6. Fig. 2 isa fragment of the transmission shaft with a ball opening therein. Fig.3, is a section on the line 33 in Figs. 1, 5 and 6, the view being fromthe right of Figs. 1 and 6 and left of Fig. 5. Fig. 4 is a section onthe line 4*4; in Figs. 5 and 6, the view being from the left of Figs. 1and (3 and the right of Fig. 5.

Fig, 6 is a section on the line 66 inFigs. 1, 3 and 4, the View being from the bottom of Fig. 1, from theleft of Fig. 3 and from the right of Fig, 4:. Fig, 7 is an enlarged viewof part of the controlling mechanism. Fig. 8 is an end view of the samemechanism. Fig. 9, an enlarged elevation of the ball actuating device ofthe controlling mechanism. Fig. 10 an end View of the same device. Fig.11 is an end view of a cam block for actuating the ball actuatingdevice. Fig. 12 a side elevation of the same block.

The device is preferably arranged in an oil tight case A, so that alubricant may be used freely with the device and atthe same time bethoroughly protected from dust.

This case forms the frame for the speed changing device and ispreferably formed of two parts, A and A securedtogether. It is providedwith an opening A which is provided with a. cover At. secured in placeby the swinging spring bar a. This is arranged to swing and be sprungunder the shoulder d on the frame so as to securely fasten the cover inplace.

.The driving shaft B is journaled in the bearing a and a The bearing ais an ranged in the case and the bearing a is arranged in post a Thelubricating rings bb are arranged on the shaft B and extend into acavity under the bearings a This cover is These rings operate in themanner common tolubricating rings. Rings bb are arranged similarly onthe bearing a and. ex tend into the cavity a beneath the hearing.

The driven shaft C is arranged in line with the shaft B. one end of theshaft being journaled in the bearing a secured in the frame or case A.This bearing is provided with the lubricating rings 0-0 which extendinto the oil cavit a beneath the bearing. The other endo the drivenshaftC extends into a sleeve-like extension B on the end of the drivingshaft, and this extension B forms one of the bearings for the drivenshaft 0-.

The transmission shaft D is parallel to the driving and driven shaftsand is mounted in the bearings a and (1 in the case. These bearings areprovided with lubricating rings (1 which extend into the oil cavities aThe transmission shaft is driven through the action of the gears B andl). The gear B is provided with a sleeve like hub 6 Ball openings b arearranged in this hub and ball sockets b are provided in the shaft B andso located as to be brought slidingly mounted on the hub b.

and thus lock the hub and gear B driving shaft B. The gear D sized gears'ings into register with the sockets b a Balls 6 are arranged in theball openings 6 cam ring B having the cam surface I) is The balls I) areof greater diameter than the thickness of the hub so that when-thesleeve B is -forc'ed toward the left as shown in Fig. 1,

balls are forced through the and extend into the sockets b with the islocked with the transmission shaft by means of the key d: -Thetransmission shafti s preferably provided with a series of different D Dand D and a reverse rovided' with the d. The transpart of the openings bear D Their bores are all sockets d, d", (it, an

vmission shaftis hollow'or in the form of a sleeve and has ball openings2', 3 4' and 5. These 0 enings are so located as to come into registerwith the sockets d, d, d and d as the transmission'shaft is rotated.Balls 2, 3 4 and 5 are arranged in the opend, d and 21, respectively andare ada ted to be forced into said sockets for locking shaft. In Fig. 2,I have shown an enlar ed view of one of these ball openings. It as thecontracted end (i which is; of slightly less diameter than that of theballs. This construction permits I the balls to project through thefopenings sufliciently to clear the transmission gears and at the sametime retain the balls in the openings when out of action. The gears D D?and D mesh the gears (3","0 and C on the driven shaft. These gears 'arelocked with 'thedriven shaft by a mechanism hereinafter described. Thereverse gear D meshes'an intermediate gear E and this intermediate gearmeshes a gear C the gear (3 being secured to the gear G by means of thescrew 0?. The

gear E is mounted on a pin a (see Figs. 3

and 5) and this pin. is carried byjthe bracket a extending from the wallof the frame. (See Figs. 3, 5 and 6.) The interposing of theintermediate gear E between the gears- D and C reverses the direction ofthe movement of the driven shaft from what, 'it' is when driven from theother transmission gears.

It will'readily be understood that as the balls 2, 3 4 and 5 are forcedout into the sockets "in the transmission gears, they lock these gearswith the transmission shaft. It will also be readily understood that notwoshould be locked with the transmission shaft atthe same'time. i

In the operation of devices of this kind,- it is desirable to throw inby acontinuous movement of the controlling mechanism the various speedssuccessively from the lowest to ,the highest and vice versa. In themech-' anism shown, the ball actuating device-F of the controllingmechanism is arranged withthe gears with the transmission in thetransmission shaft. This ball actuating device is rotatively mounted ona rod F, and is provided with a cam f. This cam has the two beveled camsurfaces f one at each end of the device. As the device is moved alongthe transmission shaft, it forces the balls controlling the engagementbetween the shaft and the translnission' gears outwardly. The device isof suflicient length to only force one set of balls into engagement at atime and as it passes by, 1t re.- leases this set of balls beforeforcing a second set of balls inposition to look a gear with the-shaft.The ordinary neutral position is between the reverse gear D and thelowest speed gear D. As it moves from this position, it first forces theballs 4 into locking position. -If a higher speed is desired, a furthermovement will release these balls and force the balls 3 into lockingposition. One of the desirable featuresof the invention is that thenumber of gears may be increased indefinitely without materiallychanging the mechanism. It sometimes-happens that the mechanism isbrought to a stop and it is desirable to be able to move the ballactuating device to a different speed or to a different position be forestarting themechanism. For this purpose, the ball actuating device F hasthe grooves f. These are of sufficient depth to permit of the passage ofthe ball actuating device F past the balls acting on the-transmissiongears, when this groove'is brought into alinement with the balls. Thiscan be done by rotating the device F-so as to bring t-helgrooves f intoline with the balls. I prefer to have this ball actuating device Frotated through the action of the balls themselves upon it, when theballs are locked in their inward position with the mechanism stationary.To accomplish this,I provide the front 'end of the. ball actuatingdevice with'theann'ular cams f These engage the cams f on a cam block FThe cam block is slidingly mounted on. the shaft F, but is lockedagainst rotative movement thereon by the key f. A spring F 'forces thecam blocktoward the ball actuating device F.

being locked against en agement by] the cotter pin F. The shoul or fprevents'an 'endwise movement of the ball actuating device F under theinfluence of the spring. At the ends of'the cams f are the shoulders fand at the ends of the cams f are the opposing shoulders f. As the ballactuating evice is moved alon the transmission shaft,"beveled eurfaces Eof the cam F" engage the balls successively. If asocket in the ear is inregister with the ball openings, the all is forced out into the socket,and rests on the comparatively flat surface of the I cam f.- If,however, the ballis held locked .130-

enera p a in its inner position by reason of the fact that the socketsare not in register, then the balls acting-upon the beveled surfaces fof the cams f turn the hall actuating device F s on the rod F into linewith the balls and permit the passage ofthe-ball actuating device pastthe balls. In this Way, the ball actuating device may be moved from endto end of its travel with the parts stationary, whether or not the ballsare in register with the sockets or not. These yieldingcams also performa useful function even when the mechanism is in acv tion, in that itpermits of the immediate movement of the ball actuating device to thedesired position even though the ball sockets are not for the moment inregister with the ball openings at the desired position, and as soon asthe sockets do move into register with the ball openings, the balls areforced into the sockets by the action of the springs operating throughthe cams f and f. The ball actuating device is shown in dotted lines inFigs. 7 and 8 as having been rotated to permit of its movement past theballs. device operate properly, the rod F" should be locked againstrotative movement. I providethe rod with the shoulder F havso mg a;perforation f. A pin f is arranged in the perforation f and throughaslot d extending axially along the shaft D. Movcment is communicated tothe rod F through this pin by means hereinafter described.

It is desirable as an added speed variation as well as a means forreducing the friction of the parts, to be able to couple the drivingshaft clirettly with the driven shaft, and the efficiency of the deviceis increased, if,

so when the driving shaft is connected directly with the driven shaft,the mechanism connected with the transmission shaft is thrown out ofaction. It is" also desirable to have this accomplished with the samecontrolling mechanism that is used to throw in the different speedsthrough the transmission shaft and tohave the mechanism so arranged thatthe direct connection between the driving and driven shaft will be inproper sequence 5 to one of the speeds (ordinarily the highest) throughthe transmission gears. In the mechanism shown, this is accomplished ina simple but efiective manner. The clutch for coupling ,the drivingshaftdirectly with the driven shaft comp ises the ball openings 7) in theextension B. Ball sockets I) are arranged on the driven shaft inposition to be brought into register with. these ball openings Balls 6are arranged in the openings.

A ball actuating ring G is slidingly mounted on the extension B" and thesleeve C on the driven shaft. It has the ball actuating ca m g and theball retaining lip 9. When this sleeve is moved toward the left as shownin dotted lines in 1, the balls 5 are forced so as to bring the groove f'ing and driven shaft. I

In orderto make the ball actuating fates in the sleeve C, thus forkedend If.

inwardly, into the sockets 19 thus locking the driving and driven shaftstogether. It is manifest. that prior to the time the driving and drivenshafts are locked together, that'the connection between the driving and70 driven shafts through the transmission gears mustb'e thrown out.This. may be done by so positioning the controlling mechanism withrelation to the ball actuating device F as to have the ball actuatingdevice in such 7a neutral position at the time the sleeve G is inposition to lock the clutch between the drivprefer, however,- not onlyto be' able to lock the driving and drivenv shafts together but at thesame time so to entirely throw out of action all the gears of thetransmission mechanism. The driven shaft gears C C etc., are mounted onthe sleeve C. vThey are locked against rotation upon said sleeve bymeans of the key 0; A 351'- clutch for locking this sleeve and conse-.quently the gears with the driven shaft C comprises the ball openings 0in the sleeve G, the ball sockets in the driven shaft in position to bebrought into register with the 93 said ball openings; the balls 0* insaid openings, the balls being of such diameterw'ith relation to thesleeve as to be forced into the I socket by the action of the sleeveG-upon them. This action on the balls is facilitated 95 by the cam surface9 on the sleeve G and the ball is retained in the opening by means ofthe retaining lip The space between the 4 cams g and g is such thatbefore the cam forces the balls 6 into locking position, the 10s Cam 9has passed the ball openings c so as to release the clutch between thesleeve C and the driven shaft, and on the return movement, the clutchbetween the'extension B and'the driven shaft is released prior to thelocking of the sleeve C with said driven shaft. Itwill-be noted that assoon as the clutch between the sleeve C and the driven shaft isreleased, this driven shaft simply ropermitting the d riven shaft gearsC G etc., to remain stationary. It is desirable also to throw out thegears B and D so that the transmission shaft itself may remainstationary when the d iving shaft is connected directly with the d rivenshaft. This is accomplished by means of clutches controlled by thesleeve B heretofore described.

Controlling mechanism for accomplish- :ing the movement of the sleeves Gand B 1 in proper sequence in relation to the action of the transmissiongears is as follows. A rod H extends without the case and may be readilymanipulated or attached to any desired operating mechanism (not shown).This rod extends through a lug h on a slide H andis' secured to this lugby means of nuts; one at each side of the lug. A bracket h extends fromthe slide H and has the Thisforlred end enters a 151 groove f in asliding collar F arranged on collar l3 so that a movement of the collarcommunicates movement to the rod FT and consequently to the ballactuating device. The slide H- is moved through the action of the rod HQAs the bracket I'I approaches the extreme end of its travel, toward theleft as viewed in ig'. 5, it contacts the roller h. The roller h iscarried by a lever 72, and lever is mounted on the sleeve H The sleeve His 'rotatively mounted on the pin H the pin I-I extending acrossthecase, and is secured to the walls thereof. The forked lever h extendsfrom the sleeve .I-I and the roller pin 71. extends from this lever intothe groove g in the sleeve G. The parts are so proportioned relativelyto each other that when the ball actuating device F reaches a positiontoforce the balls D into locking position, to contact the roller h.

nient of the slide and consequently the ball actuating device carriesthe parts to the position shown in dotted lines in Fig.1; that is, theball actuating device is moved to a position to release the ear D and tomove the sleeve G to a position locking the driving shaft directly withthedriven shaft and to release the sleeve C from the driven shaft. -Whenthe slide H is moved from the extreme position, to bring the slidingcollar into contact with the roller h a cam h on the slide is broughtint-o contact with a roller hf. This roller is" carried by a lever 71..The lever extends from a sleeve H The sleeve H is rotatively mounted ona stud or pin H. This studor pin is secured to the wall of the case.

The forked lever k extends from the sleeve and roller pins h extend fromthe forked lever into the groove 79' of the sleeve B". This cam h?forces the lever to the position shown in dotted lines in Fig.
